INSTALLATION

These instructions explain the recommended method of

installation of the PHP heat pump unit and associated

electrical wiring.

This unit is designed and approved for use as a self-

contained air-to-air outdoor heat pump system.

The units are factory equipped with a transformer and blower

control for applications without auxiliary heat. Electric heat

accessory kits (PHK) can be ordered for field installation of

additional heat where required.

These instructions, and any instructions packaged with

mating components and/or accessories, should be carefully

read prior to beginning installation. Note particularly any

CAUTIONS or WARNINGS in these instructions and all

labels on the units.

These instructions are intended as a general guide only, for

use by qualified personnel and do not supersede any national

or local codes in any way. Compliance with all local, state,

provincial, or national codes pertaining to this type of equipment

should be determined prior to installation.

IMPORTANT: The 15 SEER models have been designed

and manufactured to meet ENERGY STAR criteria for energy

efficiency. However, proper refrigerant charge and proper air

flow are critical to achieve rated capacity and efficiency.

Installation of this product should follow the manufacturer’s

refrigerant charging and air flow instructions. Failure to

confirm proper charge and airflow may reduce energy

efficiency and shorten equipment life.

Inspection of Shipment

Upon receipt of equipment, carefully inspect it for possible

shipping damage. If damage is found, it should be noted on

the carrier’s freight bill. Take special care to examine the

unit inside the carton if the carton is damaged. File a claim

with the transportation company.

If any damages are discovered and reported to the carrier

DO NOT INSTALL THE UNIT, as claim may be denied.

Check the unit rating plate to confirm specifications are

as ordered.

Limitations

The unit should be installed in accordance with all national

and local safety codes.

Limitations of the unit and appropriate accessories must also

be observed.

The unit must not be installed with any ductwork in the

outdoor air stream. The outdoor fan is not designed to

operate against any additional static pressure.

Location

The unit is designed to be located outdoors with sufficient

clearance for free entrance to the air inlet and discharge air

openings. The location must also allow for adequate service

access.

The unit must be installed on a solid foundation that will not

settle or shift. Adequate structural support must be provided.

Maintain minimum clearances as shown in Table 1 and install

the unit in level position. Isolate the base from the building

structure to avoid possible transmission of sound or vibration

into the conditioned space.

The unit foundation should be raised to a minimum of

3" above finish grade. In areas which have prolonged

periods of temperature below freezing and snowfall, the unit

should be elevated above the average snow line. Extra

precaution should be taken to allow free drainage of

condensate from defrost cycles to prevent ice accumulation.

The unit should not be located near walkways to prevent

possible icing of surface from defrost condensate.

Avoid placing the unit near quiet areas such as sleeping

quarters or study rooms. Normal operating sound levels

may be objectionable if the unit is placed near certain rooms.

Do not permit overhanging structures or shrubs to

obstruct condenser air discharge inlet or outlet.

For improved start-up performance, the indoor coil

should be washed with suitable detergent to remove

any residue from manufacturing processes.

Exercise care when moving the unit. Do not remove any

packaging until the unit is near the place of installation. An

accessory lift kit can be purchased to aid in rigging (see

Figure 1). Spreaders whose length exceed the largest

dimension across the unit must be used across the top of

the unit. Recommended spreader length: 3 ton and smaller

package units – 44", 3.5 ton and larger units – 54".

Before lifting a unit, make sure that the weight

is distributed equally on the cables so that it

will lift evenly.

CAUTION

Using Accessory Lift Kit

Figure 1

Units may also be moved or lifted with a forklift while still in

the factory-supplied packaging. The lengths of the forks

of the forklift must be a minimum of 42".

Roof Curb Installation

If a roof curb is used, follow the manufacturer’s Installation

Instructions and be sure that all required clearances are

observed (see following Clearances section).

Clearances

All units require certain clearances for proper operation and

service. Refer to Table 1 for the minimum clearances to

combustibles as well as minimum clearances necessary for

servicing and proper unit operation.

In the U.S., units may be installed on combustible floors made

from wood or class A, B, or C roof covering material. In Canada,

units may be installed on combustible floors.

Service Access

Access to all serviceable components is provided by four

removable panels: filter compartment, blower compartment,

heater compartment, and top panel.

Condensate Drain

The PHP package unit is equipped with a 3/4" FPT coupling

for condensate line connection. Plumbing must conform to

local codes. Use a sealing compound on male pipe threads.

The condensate drain line must be properly trapped and

routed to a suitable drain. See Figure 3 for proper drain

arrangement. The drain line must pitch to an open drain or

pump to prevent clogging of the line. Seal around the drain

connection with suitable material to prevent air leakage into

the return air system.

Ductwork

Ductwork should be designed and sized according to the

methods in Manual Q of the Air Conditioning Contractors of

America (ACCA).

A closed return duct system shall be used. This shall not

preclude use of economizers or outdoor fresh air intake. It

is recommended that supply and return duct connections at

the unit be made with flexible joints.

The supply and return air duct systems should be designed

for the CFM and static requirements of the job. They should

not be sized by matching the dimensions of the duct

connections on the unit.

Outdoor ductwork must be insulated and waterproofed.

Equipment is shipped for side ductwork connection. The unit

can be converted to bottom ductwork connection by

removing the duct covers located over the bottom duct

openings and placing these covers over the side duct

openings (see Figure 4).

To remove the bottom duct cover over supply opening:

1. Remove screw on cover nearest side opening.

2. Lift end of cover slightly and push to slide back screw/

pin free from duct flange.

3. Slide duct cover out the side duct opening.

Filters

Air filters are to be used with this heating/cooling unit. Filters

are not factory supplied in the unit. However, a filter frame

accessory is available from the manufacturer that allows

filters to be installed within the unit. If the filter frame

accessory is not used, a filter must be installed in the duct

work by the installer. Filters must always be installed ahead

of the evaporator coil and must be kept clean or replaced.

Dirty filters will reduce the airflow of the unit. Filters should be

sized in accordance with Table 2.

Electrical Wiring

All wiring should be done in accordance with the

National Electrical Code, ANSI/NFPA No. 70 (latest

edition); Canadian Electrical Code Part 1, CSA C22.1

(latest edition); or local codes where they prevail. Use

wiring with a temperature limitation of 75°C minimum. Run

the electric power supply through a fused disconnect switch

to the connection box of the unit and connect as shown in

the wiring diagram located on the inside of the control access

panel.

Thermostat

The room thermostat should be located on an inside wall

where it will not be subject to drafts, sun exposure, or heat

from electrical fixtures or appliances. Follow the

manufacturer’s instructions enclosed with thermostat for

general installation procedure. Color-coded insulated wires

(#18 AWG) should be used to connect thermostat to unit.

Four wires are required for cooling.

Compressor

Units are shipped with compressor mountings factory-

adjusted and ready for operation. Caution: Do not loosen

compressor mounting bolts.

Heater Kit Accessory (if used)

The unit is fully equipped for cooling operation without

auxiliary heat. A heater kit accessory may also be used.

To install the heater kit accessory (see Figure 7):

1. Disconnect the power and remove the heater

compartment access panel.

2. Disconnect the plug separating the high voltage wire

harness. Remove the high voltage wire harness plug

and discard.

3. Remove the heater blockoff by removing the four screws

holding it in place.

4. Insert the heater into the control panel and fasten in the

same mounting holes.

5. Plug the heater wiring harness into the wire harness on

the control assembly. Field wiring of the auxiliary heater

is separate from the unit power supply. Wire the power

supply wiring for the heater to the appropriate

connections on the heater kit.

6. Replace the heater compartment access panel and

reconnect the power.

Removal of Unit from Common Venting System

When an existing furnace is removed from a common venting

system serving other appliances, the venting system is likely to

be too large to properly vent the remaining attached appliances.

The following test should be conducted with each appliance

while the other appliances connected to the common venting

system are not in operation.

1. Seal any unused openings in the common venting

system.

2. Visually inspect the venting system for proper size and

horizontal pitch and determine there is no blockage or

restriction, leakage, corrosion, or other deficiencies

which could cause an unsafe condition.

3. Insofar as is practical, close all building doors and

windows between the space in which the appliances

remaining connected to the common venting system are

located and other spaces in the building. Turn on clothes

dryers and any appliance not connected to the common

venting system. Turn on exhaust fans, such as range

hoods and bathroom exhausts, so they will operate at

maximum speed. Do not operate a summer exhaust

fan. Close fireplace dampers.

4. Following the lighting instructions, place the unit being

inspected in operation. Adjust the thermostat so the

appliance will operate continuously.

5. Test for spillage at the draft control relief opening after 5

minutes of main burner operation. Use the flame of a

match or candle.

6. Follow the preceding steps for each appliance connected

to the common venting system.

7. After it has been determined that each appliance

remaining connected to the common venting system

properly vents when tested as outlined above, return

doors, windows, exhaust fans, fireplace dampers, and

any other fuel burning appliance to their previous

condition of use.

8. If improper venting is observed during any of the above

tests, the common venting system must be corrected.

See National Fuel Gas Code, ANSI Z223.1 (latest

edition) or CAN/CGA B149.1 & .2 Canadian

Installation Codes to correct improper operation of

common venting system.

OPERATION

Sequence of Operation

Cooling

When the thermostat is in the cooling mode, the O circuit is

powered which energizes the reversing valve. Upon cooling

demand, the thermostat closes circuit R and Y. Closing R

and Y closes the unit contactor, starting the compressor and

outdoor fan. The thermostat automatically closes R to G circuit

which also brings on the indoor blower at the same time. Upon

satisfying cooling demand, the thermostat will open the above

circuits and open the main contactor, stopping the compressor

and outdoor fan. If the unit is equipped with a delay timer, the

blower will continue to operate for 90 seconds which improves

system efficiency.

Heating

Upon heating demand, the thermostat closes circuit R to Y, which

closes the unit contactor, starting the compressor and outdoor

fan. The reversing valve is not energized in the heating mode.

The thermostat again automatically brings on the indoor fan at

the same time. Upon satisfying heating demand, the thermostat

opens above circuits and stops unit operation.

Defrost System

The defrost system includes two components: the defrost

thermostat and the defrost control.

Defrost Thermostat

The defrost thermostat is located on the liquid line between

the check/expansion valve and the distributor. When the

defrost thermostat senses 42°F or cooler, the thermostat

contacts close and send a signal to the defrost control board

to start the defrost timing. It also terminates defrost when

the liquid line warms up to 70°F.

Defrost Control

The defrost control board includes the combined functions

of time/temperature defrost control, defrost relay, diagnostic

LEDs and terminal strip for field wiring connections (see

Figure 8).

The control provides automatic switching from normal

heating operation to defrost mode and back. During the

compressor cycle (call for defrost), the control accumulates

compressor run time at 30, 60, 90 minute field-adjustable

intervals. If the defrost thermostat is closed when the

selected compressor run time interval ends, the defrost relay

is energized and the defrost begins.

Defrost Control Timing Pins

Each timing pin selection provides a different accumulated

compressor run time period during one thermostat run cycle.

This time period must occur before a defrost cycle is initiated.

The defrost interval can be adjusted to 30 (T1), 60 (T2), or

90 (T3) minutes. The defrost timing jumper is factory installed

to provide a 60-minute defrost interval. If the timing selector

jumper is not in place, the control defaults to a 90-minute

defrost interval. The maximum defrost period is 14 minutes

and cannot be adjusted.

A test option is provided for troubleshooting. The test mode

may be started any time the unit is in the heating mode and

the defrost thermostat is closed or jumpered. If the jumper is

in the TEST position at power up, the control will ignore the

test pins. When the jumper is placed across the TEST pins

for 2 seconds, the control will enter the defrost mode. If the

jumper is removed before an additional 5-second period has

elapsed (7 seconds total), the unit will remain in defrost mode

until the defrost thermostat opens or 14 minutes have passed.

If the jumper is not removed until after the additional 5-second

period has elapsed, the defrost will terminate and the test

option will not function again until the jumper is removed and

reapplied.

Compressor Delay

The defrost board has a field-selectable function to reduce

occasional sounds that may occur while the unit is cycling in

and out of the defrost mode. The compressor will be cycled

off for 30 seconds going in and out of the defrost mode when

the compressor delay jumper is removed.

NOTE: The 30-second “off” cycle is not functional when

jumpering the TEST pins.

Time Delay

The timed-off delay is 5 minutes long. The delay helps to

protect the compressor from short cycling in case the power

to the unit is interrupted or a pressure switch opens. The

delay is bypassed by placing the timer select jumper across

the TEST pins for 0.5 seconds.

Pressure Switch Circuit

The defrost control includes LO-PS terminals to connect an

optional low pressure (loss of charge pressure) switch. A

high pressure switch (optional) can be connected to the HI

PS terminals (see Figure 8 on page 7).

During a single demand cycle, the defrost control will

lock out the unit after the fifth time that the circuit is

interrupted by any pressure switch wired to the control

board. In addition, the diagnostic LEDs will indicate a

locked-out pressure switch after the fifth occurrence of

an open pressure switch (see Table 3). The unit will

remain locked out until power to the board is interrupted,

then re-established, or until the jumper is applied to the

TEST pins for 0.5 seconds.

NOTE: The defrost control board ignores input from the low

pressure switch terminals as follows:

• During the TEST mode

• During the defrost cycle

• During the 90-second start-up period

• For the first 90 seconds each time the reversing

valve switches heat/cool modes

If the TEST pins are jumpered and the 5-minute delay is

being bypassed, the LO PS terminal signal is not ignored

during the 90-second start-up period.

Diagnostic LEDs

The defrost board uses two LEDs for diagnostics. The LEDs

flash a specific sequence according to the condition as

shown in Table 3.

Circulating Air Blower

Depending on the package unit model, the blower motor will

be either a multi-tap PSC motor or a variable speed motor.

PSC Motor

The circulating air blower is controlled by a timing circuit in

the blower control. Timings are not adjustable.

506248-01 Page 9 of 14Issue 0902

There is no blower “on” delay after a call for heating or

cooling. Blower “off” delay is 90 seconds after the thermostat

is satisfied.

Variable Speed Motor

Units equipped with a variable speed circulation air blower

motor will deliver a constant airflow within a wide range of

external static pressures. Other features of this variable

speed motor include:

Soft Start/Stop – The variable speed motor will slowly ramp

up to normal operating speed. This minimizes noise and

increases comfort by eliminating the initial blasts of air

encountered with standard motors. At the end of a cooling

or heating cycle, the motor will slowly ramp down.

Circulation Airflow Adjustments – The controls include a

variable speed motor interface board. The ADJUST tap can

be used to raise (+) or lower (–) the airflow by 15%.

Heating and Cooling Airflows – The units are factory set

for the correct heating and cooling airflows. However, airflow

changes can be made by moving the position of the HEAT

and COOL taps (see Table 4).

Continuous Blower – The comfort level of the living space

can be enhanced when using this feature by allowing

continuous circulation of air between calls for cooling or

heating. The continuous circulation of air occurs at half the

full cooling airflow rate. To use this feature, place the

thermostat fan switch into the ON position.

Cooling Airflow Ramp Up – At the beginning of a call for

cooling, the blower will run at 80% of full airflow for 7.5

minutes. This improves the system’s moisture removal and

saves blower power during cooling start.

Reduced Airflow Operation (Dehumidification) – For

situations where humidity control is an issue, the variable

speed motor can be connected to operate at a 25% reduction

in the normal airflow rate. The variable speed motor interface

board provides for connection of a humidistat on the HUM

terminal. When a humidistat is connected, the dehumidifier

resistor on the interface must be cut. The humidistat should

be wired to open during high humidity, which will reduce

blower airflow.

Cooling System Performance

For maximum performance of the cooling system, operating

temperatures and pressure should be checked. Subcooling

should be determined at Standard ARI test conditions of 82°F

outdoor and 80°F indoor dry bulb/67°F wet bulb. If subcooling

measured deviates from values found in Table 5, refrigerant

charge should be adjusted accordingly for maximum

performance.

Periodic inspection and maintenance normally consists of

changing or cleaning the filters and cleaning the outdoor coil.

On occasion, other components may also require cleaning.

Filters

Filters should be checked at least every 6 weeks. Disposable

filters should be replaced when dirty, and cleanable filters

should be cleaned regularly. It is important to keep the air

filters clean, as dirty filters can restrict airflow and the blower

motor depends upon sufficient air flowing across and through

it to keep from overheating.

Motors

Indoor and outdoor fan and vent motors are permanently

lubricated and require no maintenance.

Outdoor Coil

Dirt and debris should not be allowed to accumulate on the

outdoor coil surface or other parts in the air circuit. Cleaning

should be as often as necessary to keep coil clean. Use a

brush, vacuum cleaner attachment, or other suitable means.

If water is used to clean the coil, be sure the power to unit is

shut off prior to cleaning. Care should be used when

cleaning the coil so that the coil fins are not damaged.

Do not permit the hot condenser air discharge to be

obstructed by overhanging structures or shrubs.

MAINTENANCE

Failure to follow the safety warnings exactly

could result in dangerous operation, serious

injury, death, or property damage.

Improper servicing could result in dangerous

operation, serious injury, death, or property

damage.

• Before servicing, disconnect all electrical

power to unit.

• When servicing controls, label all wires prior

to disconnecting. Reconnect wires correctly.

• Verify proper operation after servicing.
